Yeahh.... I know they are in there, I just don't use them. In WCIII, they selected your different heroes I think. The only game I truly used them in I believe was homeworld, as they changed the formation or tactics on your fighters, something you needed to have quick access to. That game could justify it though because all other hot keys were used.

Haha, yeah. Come to think of it, I set F8 and F6 to my 4th and 5th mouse buttons. In Starport: Galactic Empires, F8 fired nukes, and F6 dropped turrets. VERY convenient. Except I also set my push-to-talk key for ventrillo to F8... I accidentally fired off thousands of credits worth of nukes because of that...
